V In metal windows the masonry work-psitions the jambs, lintels and sills,'but:ordinarily the sills are designedto. project into the room. a For the sakeof appearance, the side edges of the sills shouldbe set the. plasterof the side; walls of the window openings. This sometimes creates difi i'culties, for;

the wallv thickness at the various openings; may vary greatly, and often the inside andoutside lines ofthe masonry workare'notabsolutely. parallel. In order to simplify the problem somewhat. met l ind havepberepn mbled with the sills divided;v i t t Portions? Sill P p p -O e by the brick work, and an extensionninto the room called a stool which iscutitomeasure inorder; to conform to-the individual window. open-- ings. Heretofore the edges of- .the stools have been plastered-into the side walls of the window openings to give a finished ap'.

pearance to the work,.but as inrmodern const-ructions, the plaster work is done in a quick sequence after the wall work, greatinconv'ene ience and some times delay resultsbecause the window companies.-must;measure andieut' each stool to the individual window. openings and-the time allowedfor this is very short. To overcome this difficulty. I arrange so' that the stoolican be put in place at. anytime 0 and'ma-y later be readily removable, by sup;

plyingchannel members which preferably are attached to the sill and areiplastered in place within the sidewalls of the window openings by the plasterers directly after the wall work is completed; Thereafter, while the plastering is being completed... the} stools may be cut to measure and positioned havingtheir side edges slipped into the ob an nel members so that the stool and sill" may be bolted together and so that the sideedges of the stools areconcealed neatly within the plaster lines. The channel members are prefr erably of U-shape and means. should: be

provided so they may be adjusted'in relation to the. sill. This permits the channels to run:

exactly upto the plaster line of the room.

This construction also possesses the advantage of allowing- .the: ready removal of the OJ stools because-their; sid-eedges are not; set in by Fig. 3. i i

Afterfthe jambs, weight boxes, sills and:

lintels are assembled as indicated in Fig; 1,

these parts are positioned by the brickwork.

the plaster.- i Further, the channel members serve as a partialsupport to :the stools; In the; accompanying drawings. I, showone form of my invention and; a modification thereof, and .it is to be understood that, these are simply illustrative embodiments of my inventive idea and that the same may be mod.- ified greatly without departinghfrom the spirit of my invention.. I

' ln-l ligsl, 1.2, Hand 4; only-one side .offth'e Window assembly is shown inasmuch as. the. other side isacounterpart therefor. In the figures, l 10, and; 12' are respectively the inner; andouter sash plates of the windows, l l and 16. The plates 10' and 12 extend into enlargediopenings l8 and 20 behind the jamby designated as21. The'weight enclosure 22 andcover 23 complete this portion of the wins. dow box assembly. LA window sill 24 hasgthecustomary break 25. indicated. I

In this type of construction a depending flange, indicated as 26 shouldbe placed upon r the inner side oft-he sill as a'stifienerand in order that the stool may be attached there-1 to by an angle iron 29. This is best shown T providean adjustableU shaped member designated as 3-1, which forms a channel.

within. the plaster forthe-edges of the stool 28, said Usha-p-ed member being adjustablyi attached to the underside of the sill so that it may extend inwardly of the room and be adjusted with room plaster line 30, as shown by Fig. 1.

U shaped member 31-has a slot 33 so that a suitable adjustment by means of a bolt 35 with the sill 26 may be made and so that the end of the U shaped member will definitely run to the edge of the room plaster line, but no further. This feature of adjustability is an important element of my invention as it provides for the variations of wall thickness in the various window openings. When U shaped member 31 is in position with the U facing the window open ing it is plastered in place so that the edges of the stool 28 may be slipped into the U. This type of assembly hides the edges of the stool in a neat and workmanshiplike manner and provides a partial support therefor.

It is evident that the depending flanges 26 of the sill shouldbe notched, or cut away at both ends, in order to admit the U shaped member 31.

The plaster work alone cannot support the stool and 1 preferably attach the stool to the sill by means of an angle iron 29, although this particular type of attachment is not necessary. A depending flange 26 strengthens the sill and makes a convenient place to aflix the stool. I prefer to have a depending flange 37 upon the front and side edges of the stool (best illustrated by Fig.

2) as this gives a finished appearance to the stoolwhich projects into the room, and also stiffens the same. f

As shown by Figure 4, the U shaped member 3l-will ordinarily have a larger lower flange than upper, but will have the upper flange provided with a wide end 31a to allow a slot 33 to be formed, but this mode of construction can be readily varied. It is to be understood that the novelty of this invention as shown by the illustrated structure, consists in the provision of adjustable channels for the edges of the stool. It is this provision of channel members which permits immediate plastering of the channels after the installation of the main window parts and l have shown in Figs. 5, 6, 7, 8 and 9, a simple modification of the preferred form.

The form of the adjustable means to attach the channel members to the sill and the shape of the channel members can be varied at will. As shown by Figs. 5, 6, 7, 8 and 9,

I have illustrated a type of adjustable channel member in much the same fashion as the other figures, and have numbered the common parts by the same numbers. However, as particularly shown by Figs. 8 and 9, the shape of the channel member 31 is modified and the channel member is made adjustable by being slipped into a U shaped slotted guide m all, said slotted guide preferably having a depending flange 43 so that the U shaped member may be firmly held between flange 4:3 and the depending flange 45 at the side of the sill. Slotted guide 41 should be supported by the under side of the sill by bolts or screws 42. It is apparent that more or less obvious equivalents for the member ll could be improvised and that corresponding changes in the shape of the U shaped channel, even including a change in the depending flange 37 ofthe stool, could be made without departing from the spirit of my invention.

It will be observed from the foregoing description that my invention essentially consists, in this type of window, in the provision of adjustable channel members which may be plastered in the side walls of the window openings at once after the preliminary window work is done, thus avoiding the de lays attendant in the cutting of the individual stools, these channel members further serving as a partial support to the stools, and allowing the stools to be installed, or to be removed if desired, without disturbing the side wall plaster of the window openings, although because of the channel members the side edges of the stools are buried within the V adjusted inwardly or outwardly with relation to the sill.

2. In a metal window, a sill adapted to be positioned by the masonry work, a still provided with means for attachment to said sill and adapted to project into the room, channel members adapted to be plastered within the side walls of the window opening and to receive the side edges'of said stool, and means for adjustably positioning said channels relative to said sill. I

3. A structure as specified in claim 2 in which the means for positioning said channels relative to said sill comprises members, attached to the underside of the sill, forming slots adapted to receive said channels and in which said channels may slide.

4. A metal window comprising a sill and a stool adapted to be attached thereto, adjustable U-shaped channel members provided with elongated slots for adjustable attachment to the underside of said sill by bolts and adapted to serve as channels for the edges of said stool, said channel members being longer than the distance from the sill. tothe plaster line of the room whereby said channel members may be positioned so that channels for said stool edges run from the plaster line of the room to the sill.

5. In a metal window, a metal sill having a depending flange upon its inner edge, a metal stool for attachment to said sill so that the stool extends inwardly of the room, and metal channel members longer than the distance from the sill to the wall plaster line being provided with slots for adjustable attachment to said sill, said channel members being adapted to be plastered within the plaster of the side wallsof the window openings with the channel opening towards the window openings whereby the edges of said stool maybe slipped into said channels.

6. In a metal window, a sill with a depending flange upon its room side, said flange being notched at both ends, a stool for attachment to said sill, channel members provided with a channel adapted to receive the side edges of said stool, said members being of sufficient length to run from the sill to the room plaster line, and means for attaching said channel members to the underside of the sill in adjustable relation thereto, whereby said channel members may run from the underside of the sill through the notches of the sill flange and be fixed in the plaster with the channels facing the window opening and running to the wall plaster line, thus permitting the stool edges to be slipped into said channels. i

10. Awall construction comprising a plastered wall, a window opening therein, a metal window comprising a sill and a stool adapted justably supported by said sill and adapted for plastering and setting into the walls of for attachment thereto, channel members adsaid window opening so that the members 7 run from the sill to the room plaster'line with the channels facing the window opening, said I channel members being further adapted to receive the side edges of said stool whereby the stool edges may be slipped into the channel members and the stool brought to abut the sill. i
